We have seen massive inflation in asset prices. Just look at housing and the stock market, both of which took off after the Financial Crisis. This is the primary cause of the massive income inequality we see these days, because poor people can't afford houses and stocks but upper middle class and wealthy people can and do.

Housing, schooling, and healthcare are necessities that people will go deeply into debt to be able to afford. They will pull money out of their retirement to bid on houses or pay for their kids college. They will mortgage anything, and beg from friends and family, to afford healthcare.

These three items are well known to have costs that have risen above inflation for decades.

I offer an alternative explanation: these three items are so vital to people that they will sacrifice spending in other areas to support these costs. All of the unmeasured inflation of the past decades is represented solely in these items.
